Hi Stephen,

The kernel's ./Documentation/devicetree/bindings/net/stmmac.txt mentions that Required properties:
- phy-mode: See ethernet.txt file in the same directory.
- snps,reset-gpio gpio number for phy reset.
- snps,reset-active-low boolean flag to indicate if phy reset is active
low.
- snps,reset-delays-us is triplet of delays
The 1st cell is reset pre-delay in micro seconds. The 2nd cell is reset pulse in micro seconds. The 3rd cell is reset post-delay in micro seconds.
Sorry, I just saw you replying again before, stmmac.txt was found, this reply email please discard.
